Figure 1.
Schematic representation of the normal (A) and Met-modified (B) glycinin chimeric genes. White and shaded boxes indicate the coding region and the 5′ and 3′ noncoding regions of glycinin cDNA, respectively. Thin and light-shaded lines depict vector DNA. Arrows indicate direction of transcription. 35S Pro, CaMV 35S promoter; Bar, the bialaphos resistance gene; Nos Ter, nopaline synthase gene terminator; g7, gene 7 terminator; Glutelin Pro, GluB-1 promoter; Glycinin cDNA, preproglycinin A1aB1b cDNA; Glutelin Ter, GluB-1 terminator; R, right T-DNA border; L, left T-DNA border.
